Answer:
B. Reduce the Money Market Fund allocation by 30% (to 10%) and put the released funds in AAA-rated corporate bonds
Step-by-step explanation:
First of all, since the investor is risk averse and cannot afford to lose money on any risky investment, she should change the mix of her investment portfolio but without increasing risks. Corporate bonds that are AAA-rated carry a very low risk and pay a little higher than money market funds. So a small decrease in money market fund assets and an increase in AAA-rated bonds should yield a slightly higher return.
Investing in equities would be too risky and US Treasuries pay even less interests than money market funds.
